[0002] The damage of mites has always been a headache for growers, because after they damage the leaves, many small white spots will appear on the leaves, the chlorophyll will be destroyed, and the luster will be lost, which will cause the plants to fail to perform normal photosynthesis, resulting in leaf fall and yield reduction
At the same time, due to its overlapping times, large number of reproduction, and frequent use of medication, it has developed resistance to the currently commonly used acaricides.

Abstract
The invention discloses a fluazinam and cyenopyrafen compounded acaricidal composition. The effective components of the acaricidal composition are fluazinam and cyenopyrafen, a weight ratio of fluazinam to cyenopyrafen is 20:1 to 1:20, and the acaricidal composition concretely comprises, by mass, 1-49% of cyenopyrafen, 1-49% of fluazinam, and the balance of assistants; the dosage of the acaricidal composition is a water suspension, an oil suspension, a water dispersible granule or a wettable powder; and the acaricidal composition mainly used for preventing and controlling herbivorous aphids on vegetables, fruit trees, tea trees, cotton and ornamental plants. The composition is an acaricidal binary compounded composition, and the effective components are fluazinam and cyenopyrafen, so the composition is resistant to rain erosion, and has effects on eggs and various mite states, and the two effective components are compounded to make the composition have the advantages of resistance delaying, good quick-acting property, long lasting period, prevention of plant diseases, and saving of time and labor.
Description
technical field [0001] The invention relates to a composition for preventing and controlling mites and a preparation method thereof, in particular to an insecticidal composition whose active ingredients are fluazinam and pyrazafen and a preparation method thereof. Background technique [0002] The damage of mites has always been a headache for growers, because after they damage the leaves, many small white spots will appear on the leaves, the chlorophyll will be destroyed, and the luster will be lost, which will cause the plants to fail to perform normal photosynthesis, resulting in leaf defoliation and yield reduction. At the same time, due to its overlapping times, large number of reproduction, and frequent use of medication, it has developed resistance to the currently commonly used acaricides. [0003] As a fungicide, fluazinam has a good effect on citrus sandy skin disease. In the actual application process, we found that fluazinam has a good control effect on citrus sp...
